Have you looked into the French Tartans. Hamish, "The Kilted Legend" has a kilt in the Breton Tartan that he got from "Maison du Kilt" in Paris and it is wonderful.
If price is not your only consideration I would take a look.

I could't take a look: they have no website . So I phoned. In general, Bretons tartans are indeed wonderful . I phone the gentleman of "La Maison du Kilt" and unfortunately, he didn't have a clue what 16 oz. meant.
He humbly confessed that they served as a link between non-anglophone French and "Scotland"... from where they ordered kilts and so forth.

And, it's not only a question of price. I am well aware that I will keep and cherish this tartan for the rest of my life (especially at my age ) , but it is a question of principle. If I can save 40€ on fabric, I can feed for my family for a week. And for a Scotsman, especially one expatriated for 450 years, that counts. I dont see why I should pay more than the true value.

Voilà mon ami.
